Bobby Brown on Ex-Wife Whitney Houston: ‘You Have to Move On’ (Video)

Bobby Brown is grieving for his ex-wife, deceased pop singer Whitney Houston, but that doesn't mean he plans to get stuck in the past — even if that past was a little less than a week ago.

Brown, who's currently on tour with New Edition, performed with the group in Upper Marlboro, Md., on Thursday night, and paid tribute to Houston during a speech in which he noted, "You have to move on sometimes."

Houston died in her Beverly Hilton hotel room on Feb. 11, prior to producer Clive Davis' annual pre-Grammys bash. The singer, who was found submerged in her bathtub by a member of her personal staff, was 48. The cause of her death has not been announced, pending the results of a toxicology test.

Brown will reportedly attend Houston's funeral, which takes place noon Saturday at the New Hope Baptist Church in Newark, NJ, which Houston attended and sang at as a child. Kevin Costner, Alicia Keys, Stevie Wonder, Tyler Perry and Aretha Franklin are among those who will speak and perform at the service.
